UNITED srArns PATENT I OF ICE.

WILLIAM W. ROBERTSON, OF BENTON, MISSOURI.

Be it known that I, WILLIA W. ROBERT- SON, a citizen of the United States, residing at Benton, in the county of Scott and State of Missouri, have invented a new and useful Tobacco-Pipe, of which the following is a specification.

This invention relates to a tobacco-pipe,

cigar-holder, or the like of that type havlng a valve for controlling the smoke-passage, so

that smoke can'be readily drawn through the passage without the danger of saliva en' tering "the same through the mouthpiece, thereby maintaining the passage dry and clean and preventing the accumulation of nicotin therein.

The invention has for one of its objects to provide a stem for a pipe orcigar-holder pro-- vided with a valve WllllOh' will automatically openunder the inhalation of the smoker 'to permit a draft of smoke-through the smokepassage and automatically close when the suction or inhalation ceases and a means whereby the valve can be held open, so that a pufl of air can be blown through the smokepassage by the smoker for cleaning the same rom clogging material.

A further object of the invention is the employment in connection with a stem of this character of a saliva-chamber in which the saliva that may flow in through the passage of the mouthpiece will collect and from which the saliva can be blown out through a nor- I mally plugged opening.

Another object of the invention is toprovide a device normally contained in the smoke-passage in contact with the wall thereof so arranged that it may be reciprocated for the purpose-of loosenin any matter that mi ht collect on the wal of the passage, an thus facilitate the cleaning out of the passage by the current of air blown through the same bythe smoker; and afurther object is to provide a bowl for a pi e and a casing there or in which the bowl is removabl supported, thereby permitting the bowl to be renewed when desired.

With these objects in view and others, as

will appear as the nature of the invention is better understood, the invention comprises the various novel features of construction and arrangement of parts, which will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying pdrawings, which Specification of Letters Patent. Application filed July 27, 1906. Seria1No.328,110.

illustrate an embodiment of the invention; Figure 1 is a longitudinal section of a pipe. Fig. 2 is an enlarged detail sectional view of the pipe-stem. Fig. 3 is a transverse" section on line 3 3, Fig. 2. Fig. 4-is a perspective view of the pipe-bowl. Fig. 5 is a longituthe bowl-section of a pipe, 2 the stem-section,

and 3 the mouthpiece. The bowl-section 1 comprises a bowlpro er, 4, which is prefer-' ably molded or cast o any'suitable material, such as aluminium, and formed with a tubular neck 5, that forms part'of the smokeassage communicating with the interior 0 the bowl. .The end of the neckn5 is enlarged at 6 and internally threaded, so as to receive the threaded end 7 of the pipe-stem.

Around the bowl and neck thereof is a desired shape and, if desired, embossed with any suitable ornamentation. The top of the inwardly, so as to embrace the u'pper-end o the bowl, the said end and flange being flush, so as to produce a smooth finish. The part of the bowl-casin at the enlargement 6 is provided with an inwardly-extending flange 10, against which the end surface of the enlarge'ment 6 abuts. The bowl is removabl held in the casin by means of a spring-late .11, secured to 51c bowl, preferably at the. exterior thereof. The free end of the latch is offset, so as to produce a recess 12,that'engages over the flange 9 of the casing. The casing is preferably spaced apart from the Fig. 6 is a similar view of a coup-' dinal section of an attachment-socketjto be,

casing 8, which may. be and preferably is "made of sheetaluminium formed into the casing is formed with a flange 9, extending bowl at such a distance as to provide an Ioc am le dead-air space, he ept relatively cool. a

so that the casing may aluminium, so as to comprise atubularbody 10 13 and a central tube 14, integrally connected with the liody 13 at one en by the wall or head 15, said tube forming the main portion of the smoke-passage. The tube 14 and body 13 arev suitably spaced apart, so as to 3 a conical valve-seat 17, on which seatsthe ball-valve 18 for controlling communication between the smoke-passage and the passage 19 of the mouth iece 3. In the wall of the chamber 16, pre erably at the top side ofthe 10 body 14, is an opening 20, normally closed by a stoper or threaded plu 21 andthrough whic the chamber 16 is rained of saliva. The mouthpiece 3 is of the usual construc tion and may be made of amber, horn, or

r 5 other suitable material, and preferably curved in the form shown when used,for a pipe.

\ When the stem is to be used as a cigar-holder,

astraight mouth iece will be more satisfactory. The end of the body 13 to which the mouth iece is attached is preferably internallyt eaded to the proper size, so that mouthpieces of standard manufacture may be employed.

The valve 18 is normally held on its seat bya helical compression-spring'22, that 0 :sage 19 of the mouthpiece.

A 5 smoke-passage.

passes into the valve at oneend and rests on the inner surface of the mouth iece at its opposite end. The spring is he (1 in place by extending one terminal thereof into the pas- If desired, the spring may be passed through the valve and into the smoke-passage, where it is preferably coiled, as indicated at 23, so that the convohltions will engage the wall of the The spring 22 and the coil 23 will be of sufliciently light tension that the valve will readily unseat under the suction produced by the smoker. Adjacent the valve is arranged a device for holding the 0 latter off its seat when it is desired to blow Out the smoke-passage This device comprises ashaft 24, mounted in a bearing 25, secured to the body 13, and a finger 26 at the inner end of the shaft, that engages one of the convolutions of the spring 22, so that as the whereby it is rocked. This device for unseat-.

the smoker.

shaft is rocked in one direction the spring can be compressed and the valve drawn off its seat. The shaft 24 extends outside of the pipe-stem and is provided with a crank 27,

when a puff of air is forced through the smoke-passage the -material can be blown out through the bowl.

In order to adapt the stem for use as a cigar-holder, the attachment shown in Fig.

5 is employed. This comprises a body 28,

body 31, that is bored and threade that is bored at one end at 29 and tapped, so as to screw on the threaded stub portion 7 of the stem. The opposite end of the body is provided with a tapering socket 30 for the reception of the cigar. It may also be desirable to use the stem in connection with a cob or other pipe that is not provided with or internally-threaded socket for receiving the stub portion 7. For this purpose a frustoconical coupling attachment, such as shown in Fig. 6, is employed. This com rises a at one end, as indicated at 32, for receiving the portion -7 of the stem. Extending from the tapped bore 32 is a central passage 33, that communicates with the bowl of the pi c.

From the fore oing. description, ta 'en in connection with t 1e accompanyin drawings, the advantages of the construction and of the method of operation will be readily appreciated by those skilled in the art to which the invention appertains.

In operation the valve 18 will automatically unseat to permit the puffs of smoke to be drawn through the smoke-passage and to automatically return to its seat when the draft for each puff ceases, thereby effectively preventing moisture or saliva from entering the smoke passage of the stem. Any saliva that passes inwardly through the mouth piece collects in the chamber 16,, from which it can be readily ejected by removing the plug 21 and turning the pi e over, so that the drain opening 20 wil be lowermost. When in this position, the smoker discharges a strong pufi of air throu h the assage 19 of the mouthpiece and t e chain er 16, so as to carry out of the latter the saliva which it contains. It will be noted that during this 0 erartion the valve 18 will be ermanentl held on its seat, so that no sa iva can be If lown into the smoke-pass e.

the smoke-passage should become 0 ogged with ashes or other material, the valve 18 will be held open by turning the crank 27 rearwardly, and then a strong current of air is blown through the pipe, thus clearing out the passa e, it bein of course understood that the p ug 21 will ave been first inserted in the opening 20.

I have described the princi le of operation of the invention, together wit the apparatus vwhich I now consider to be the best embodiment thereof; but I desire to have it understood that the apparatus shown is merely illustrative and that various chan es may be made when desired as are within t e scope of the invention.
